Abstract
A disposable infant's diaper includes a wrapper comprising a unitary sheet having a base panel affixed to the diaper back section to form a pocket within which the balance of the wrapper sheet is contained. When the diaper is soiled and the user wishes to dispose of it, pulling an end panel of the sheet from the pocket unfolds the sheet to present lateral flaps bounding a center panel, while the sheet remains affixed to the diaper. The diaper is over-folded onto the sheet center panel, after which the lateral flaps are sequentially over-folded atop the diaper and respectively sealingly attached in place. The complete encapsulation of the diaper is achieved following the over-folding of the sheet end panel atop the previously manipulated lateral flaps. Alternative folded configurations of the wrapper sheet are contemplated.
